technically both plutonuim and uranuim wont work.
when ur lookin at plutonuim or uranium for example pu-239 or uranuim-235
To be considered fissile, an isotope's atomic nucleus must be able to break apart or fission when struck by a slow moving neutron, and to release enough additional neutrons in the process to sustain the nuclear chain reaction by splitting further nuclei, in other word plutonium when in its dormant state is only harmfull if exposed to skin, and it can be tarnished if exposed to oxygen.its not a dizaster yet.

only during the nuclear reaction and release of all the binding electromagnetic energy taht is often equal to tens and thousands of tons of tnt does it become dangerous which at that split second there is no more box.
